Highlights

• Results for a further eight surface holes and ten underground holes at Sao Chico since the previous exploration news release of 3 March 2020. 
• The new surface drill hole results included significant intersections of:
  • 5.30m @ 12.10g/t Au (Hole: 20-SC-166)
  • 3.40m @ 3.94g/t Au (Hole: 20-SC-164)
• The new underground step out drill results included high grade intersections within the upper portion of the main vein of:
  • 1.37m @ 28.77g/t Au (Hole: 20-SCUD-341)
  • 2.72m @ 5.06g/t Au (Hole: 20-SCUD-343)
• Diamond drilling demonstrates the Main Vein structure now continues to host gold bearing mineralisation for approximately 375 metres to the west of the current mine limits, an extension of a further 75 metres.
• Reverse circulation percussion drilling on the Cicada terrestrial geophysics anomaly indicates the strong likelihood that the anomaly is a western extension of the Sao Chico vein structure, approximately 1,000 metres to the west of the current mine limits. Results include:
  • 3m @ 2.09g/t Au (Hole: SCRC-004)
  • 1m @ 1.17g/t Au (Hole: SCRC-007)
• Regional geochemical sampling has highlighted an area, referred to as Mata Cobra, which represents an eight kilometre by two kilometre soil copper anomaly exceeding 100ppm.  This anomaly is coincidental with multiple molybdenum, bismuth, tellurium and arsenic (“Mo±Bi±Te±As”) multi-element anomalies as well as the original airborne electromagnetic (“AEM”) anomalies. 
• Within the Mata Cobra copper anomaly, located approximately five kilometres to the south of Palito, numerous significant new gold and/or multi-element anomalies have also been discovered including:
  • Ganso Prospect, a gold geochemical anomaly over a one-kilometre strike with ≥1g/t gold in soils, coincidental with the AEM anomaly.
  • The Calico, Forquila and Juca gold geochemistry and AEM coincident anomalies.  Field mapping indicates porphyritic intrusions and hydrothermal alteration amongst the host rocks of the anomalies.

Mike Hodgson, CEO of Serabi, commented:

“These results follow on from the exploration news issued on 3 March 2020, with further encouraging results as we test the western extension of the Main Vein at Sao Chico.  The underground drilling focused on the shallow portion of the Main Vein immediately beyond the mine’s western limit and returned 1.37m @ 28.77g/t Au  (20-SCUD-341) and 2.72m @ 5.06g/t (20-SCUD-343), both very encouraging.

“Surface drilling targeted the deeper portion of the main vein and its westerly extension, and results again demonstrate good depth and grade continuity, with intercepts of 5.30m @ 12.10g/t Au (20-SC-166) and 3.40m @ 3.94g/t Au (20-SC-164).  The intercept in 20-SC-166 is 300 metres below surface, and immediately down dip of 20-SC-164 and 20-SCUD341 & 20-SCUD-343, with all holes demonstrating mineable widths and grades.  On a long section, an interesting high-grade zone is clearly evolving.  

“Further west we have new holes 20-SC-167, 169 and 170.  These are the three most westerly holes and all three intersected the Main Vein with the clearly defined vein/alteration being visible.  Whilst the grades returned from the intersections (hole 20-SC-170 graded 1.00m @ 1.09g/t Au) are quite low, this is not unusual and most importantly the intersections demonstrate continuity of a gold bearing structure that is still going strong in our most western hole, now located 375 metres west of the current mine workings.     

“The Cicada terrestrial geophysics anomaly is located approximately 700 metres further to the west of hole 20-SC-170.  We have been undertaking reverse circulation (RC) drilling over this area targeting the series of high chargeability anomalies defined from the extensive ground induced polarisation (“IP”) surveys completed in 2018 (news release dated 28 November 2018).  We chose RC drilling as a quick test to confirm the potential of the Cicada geophysics anomaly and are delighted to report numerous very positive results with a number of intersections grading gold and the geology indicating strong zones of alteration and associated sulphides.  RC drilling does not provide core, but a bulk one metre down hole sample, for each metre drilled.  Any gold mineralisation intersected is therefore diluted in the sample over at least one metre.  The best intercept returned to date has been from drill hole SCRC004, where 3.00m @ 2.09g/t Au was recovered from a depth of 169 metres including a zone of 1m @ 5.42g/t Au.  Again, a long section, which shows the location of the RC programme over Cicada and the step out drilling going west from Sao Chico, clearly suggests that as we continue to drill in the gap, the two areas of mineralisation could ultimately connect.

“We have also been conducting a geochemistry programme to the south of Palito, following up on some of the findings from the AEM survey completed during 2018, which identified, in particular, the very prominent 14 kilometre long, east-west trending, magnetic anomaly known as the Mata Cobra lineament and the adjacent NE-SW trending Cinderella shear.  Since mid-2019, we have been busy with a regional geochemical sampling campaign in and around the Mata Cobra belt, and can now report that the prospectivity of the Mata Cobra geophysical magnetic anomaly has been strengthened by the identification of a eight kilometre by two kilometre copper anomaly with analytical results over 100ppm, coincidental with the geophysical anomaly identified by the AEM.

“Within the contours of this 100ppm copper anomaly, we have identified some very exciting prospects, these include Calico and Juca, at the west end of the corridor and approximately five kilometres south of Palito.  Both of these prospects exhibit a very similar geological setting to Palito and anomalous gold grades in addition to the copper.

“In the central part of Mata Cobra corridor, the Ganso, Quibe and Tabereba geochemical prospects have been identified also on strong AEM anomalies, themselves a good indicator of sulphide mineralisation.  We will continue to advance these prospects through to discovery drilling stage as soon as we can, but I am certainly very encouraged by the obvious potential that exists in the exploration ground between the Palito and Sao Chico orebodies.

“On the operations front we have enjoyed another good month in April with final production expected to be approximately 3,400 ounces and we are starting to be able to change over a small number of staff each week who have been tested for COVID-19 and undertaken a period of quarantine.”

Regional soil geochemistry sampling has been ongoing since mid-2019 with over 12,000 samples collected to date. The programme is targeting the geophysical anomalies derived from both terrestrial IP and the AEM anomalies derived from the 2018 HeliTEM survey, and the results to date have been extremely positive.

Cinderella Shear/Red Sun

Soil sampling commenced on the Cinderella Shear Zone lying approximately two kilometres east of the Sao Chico operations. This target is a significant NNE-SSW striking shear (>7 kilometres) indicated by airborne magnetic interpretation containing coincident IP chargeable and resistive anomalies and sporadic shallow EM anomalies.

The Cinderella shear has yielded a series of NNE-SSW linear gold in soil anomalies coincident with the IP chargeability anomalies in the central and southern part of the shear supported by a number of >1g/t rock chip samples recovered from sub-copping basement in the area.

In the northern part of the Cinderella shear a broad E-W trending gold in soil anomaly coincident with IP and AEM anomalies has been delineated. This anomaly, referred to as the Red Sun prospect, is positioned over an extensive area of artisanal mining activity and adjacent to a large copper-in-soil anomaly and given its location is interpreted to be a continuation of the hosting structure for Sao Chico, on the eastern side of the Cinderella shear.

Mata Cobra Corridor

Soil sampling grids were completed over the priority AEM (HeliTEM) anomalies lying along the northern and southern flanks of the major E-W trending high magnetic feature. Subsequently these grids were extended and infilled to provide a continuous systematic coverage along the flanks of this magnetic feature.

Soil results defined an extensive copper in soil (≥50ppm) anomaly extending approximately 14 kilometres E-W along this magnetic feature and referred to as the Mata Cobra Corridor. Within this broad geochemical corridor, a series of higher tenor copper-in-soil anomalies are apparent, many coincident or proximal to AEM anomalies. The regional soil contours plan (included in this news release as Figure 3) highlights a number of these higher copper-in-soil (≥100ppm) anomalies that are coincident with AEM anomalies, including Juca, Forquila, Quibe and Tabereba.

The soil geochemistry also delineated a number of robust gold-in-soil anomalies within the Mata Cobra Corridor or immediately adjacent to the copper anomaly. Prospects such as Calico, Mata Cobra East and Ganso were derived from anomalies of gold associated with other elements but with lower levels of copper.

The Calico Prospect, defined by a broad three kilometre by three kilometre soil geochemistry contour of greater than ≥10ppb of gold, contains a series of NW-SE trending stacked ≥30ppb of gold anomalies, with the highest results exceeding 500ppb of gold.  This target shows many similarities in direction, scale and tenor to the geochemistry signatures of the areas around Palito located just five kilometres to the north.

The Ganso prospect, eight kilometres to the west of Calico, is immediately overlying a priority AEM target, and comprises an E-W trending gold in soil anomaly >1g/t over a strike length of 1.2 kilometres supported by rock chips with grade of  >1g/t Au and a multi-element base metal (-Cu) anomalism.

Regional soil sampling crews continue to further develop and refine these targets as well as continuing to target other AEM anomalies in the northern portion of the Jardim do Ouro tenement portfolio. The objective is to have a series of drill ready targets defined in readiness for the resumption of drilling activities post the COVID-19 crisis.

Prospect Scale Mapping

In conjunction with the regional soil sampling programs, Serabi have been undertaking prospect wide field mapping activities to enhance our understanding of the multi-element soil geochemistry results being generated,

Serabi geologists have, over many years, developed an understanding of the Palito area and its mineralisation and geological setting and in turn the importance of alteration types, mineralisation models and associated mineralogy, has honed the wider regional understanding.  

Field mapping over soil geochemistry/AEM coincident anomalies at Calico, Forquila and Juca prospects has identified evidence of potassic hydrothermal alteration within float and outcrop samples and evidence of porphyritic type intrusions with subordinate sulphide species. 

A number of discrete Mo±Bi±Te±As multi-element cores within the broader copper anomalous area are coincident with AEM anomalies and proximal potassic hydrothermal alteration suggesting multiple shallow intrusive centres lie within the “Mata Cobra” geochemical corridor.

The mapping activities have enhanced the potential for discovery of intrusion based mineral systems. These systems can be mid-level crustal Intrusion Related Gold Systems (IRGS) or shallower crustal level Porphyry type copper/gold/molybdenum intrusives as possible causative models for the geochemical/geophysical and geological anomalism being discovering within the tenement portfolio.
